Underground diaphragm wall foundation pit supporting structure and construction method thereof
The invention relates to an underground diaphragm wall foundation pit supporting structure and a construction method thereof, and belongs to the field of foundation pit supporting. The supporting frame comprises a hollow frame body, a supporting plate is arranged on the side, abutting against the side wall of the foundation pit, of the frame body, and a plurality of through holes are formed in the supporting plate; the inclined plate is arranged in the frame body, the bottom end of the inclined plate is connected with the supporting plate, and a water containing cavity is defined by the inclined plate, the supporting plate and the side wall of the frame body. The water pumping mechanism comprises a water pumping pipe extending to the middle of the water containing cavity, and the water pumping pipe is connected with a water pump. The structure has the advantages that part of seepage water on the side wall of the foundation pit can be rapidly drained, the overall drainage pressure of the foundation pit is reduced, and the structural strength of the foundation pit is guaranteed; 2, as the pumping lift is short, the pumping efficiency is high, the difficulty is low, the requirement on the lift of the water pump is low, and the purchase cost of the water pump is saved; the residual water body can increase the overall mass of the supporting frame, the gravity center height of the supporting frame is reduced, and the stability of the supporting frame is better.
本申请涉及一种地下连续墙基坑支护结构及其施工方法，属于基坑支护的领域，其包括支撑架、斜板以及抽水机构；支撑架：包括内部设置中空的架体，架体与基坑侧壁相抵一侧设有支撑板，支撑板上开设有若干通孔；斜板设于架体内且底端与支撑板相接，斜板、支撑板与架体侧壁围合成容水腔；抽水机构：包括延伸至容水腔中部的抽水管，抽水管连接有水泵。本申请具有1、可以快速的排出部分基坑侧壁渗水，降低基坑整体的排水压力，保证基坑的结构强度；2、由于抽水扬程短，因此抽水效率高，难度低，对水泵的扬程要求低，节约水泵采购成本；3、残余水体可以增大支撑架的整体质量，降低支撑架的重心高度，支撑架的稳定性更佳的效果。
